Welcome to the forums.

Not quite following you.

You connected the AC and the system seemed to operate normally.
You then connected the battery and the system still worked normally ?

A few hours later you get a trouble tone. That trouble should show up on the keypad. It may be low battery.... or bad battery at this point..... or a communications problem if it's a monitored system.

when i connect ac alone works, normal (shows battery trouble)
and then i connect the battery, which means both AC and battery connected, and keypad no working.
worked 2 times now for around 1 mins each time, lights on everything and then dead until now
just keypad no working

Your battery may have failed so badly that when you connect it, it drags the whole system down. If that battery is more than 5 years old, it's a pretty good chance that's what's happening.
